MS35338 Split Lock Washers
MS35338 Split Lock Washers
(OP)
We call out MS35338-40 split lock washers on the drawings which are steel, cad plated. For some reason the buyers want to see if MS35338-40M split lock washers are a suitable sub for them. I'm guessing the difference is in the plating but I can't find the spec for the MS35338-40M. Is there a spec or list that shows MS35338-40M as an acceptable sub for MS35338-40 or does anyone have access to the MS35338-40M spec they can share with me? Thank you for the help.

But that copy (valid up to 2002 not 1966) doesn't have a "-40M" so I don't know where your customer gets the "M", unless the NASM conversion of the document introduced it. You may have to buy the spec from IHS, even though it may be just to tell your customer "no".
As an aside... You aren't still relying on these for fastener locking are you?

The reason the PIN was not changed when the design standard number changed was precisely for the situation daxmann is facing. Keeping the same PIN did not force companies manufacturing heritage/legacy products to issue engineering changes for every affected standard part.

I totally agree that using this lock washer seems like a poor choice. But I have also seen split lock washers commonly used with small (ie. no. 4) threaded fasteners for things like electrical connectors.
